Liberalism is one of the most influential theories in international relations, offering an optimistic counterpoint to the pessimism of realism. While realists emphasize power and conflict, liberals highlight cooperation, democracy, and individual rights as key drivers of global politics. Liberalism has evolved from Classical Liberalism, with its philosophical foundations in the Enlightenment, to Neoliberalism, which emerged after World War II to explain cooperation in an interdependent world.

Core Principles of Classical Liberalism
Classical liberalism is grounded in the values of equality, liberty, rationality, and property. It is fundamentally an individual-centered approach, viewing humans as rational actors who are free, equal, and entitled to natural rights.
- Role of the State: According to liberals, the state should act as a neutral arbiter, ensuring that individual rights are protected while avoiding excessive interference in society.
- Democracy: Liberal thought holds that democratic systems safeguard individual freedoms and reduce the likelihood of war.
- Economic Freedom: Free markets, private property, and limited government intervention are seen as the foundations of prosperity and stability.
Philosophical Foundations
Liberalism in international relations draws on a long intellectual tradition from the 17th to 19th centuries:
- John Locke: Advocated the social contract and the protection of natural rights, establishing the principle that legitimate authority derives from the consent of the governed.
- Hugo Grotius: Considered one of the fathers of international law, he emphasized legal principles and the role of rules in maintaining social order among states.
- Montesquieu: Linked political systems to patterns of war and peace, arguing that authoritarian regimes are more prone to conflict than liberal ones.
- Jean-Jacques Rousseau: Placed sovereignty in the hands of the people, with majority decision-making guiding collective outcomes.
- Immanuel Kant: Proposed that democracy, justice, and international law could foster a “perpetual peace.” His ideas inspired the concept of the “democratic peace theory.”
- Adam Smith: Championed economic freedom and the harmony of interests through free trade, laying the groundwork for liberal economic thought.
- Herbert Spencer: Distinguished between coercive military states and peaceful industrial states focused on welfare and cooperation.
Core Assumptions of Classical Liberalism
- The state works for the public good, protecting rights and freedoms.
- Limited government allows the private sector to flourish.
- International relations are win-win, not zero-sum.
- Power is not only coercive but also a tool for cooperation.
Neoliberalism: International Liberal Theory
In the aftermath of World War II, liberal thought adapted to the realities of the Cold War and increasing globalization, leading to the rise of Neoliberalism. This modern variant of liberalism emphasizes institutions, interdependence, and cooperation.
- Multiple Actors: Unlike realism’s state-centered view, neoliberalism recognizes the role of individuals, societies, and international institutions.
- State as Representative: States are seen as representatives of their societies, and conflicts often reflect domestic political choices.
- Impact of Domestic Politics: Internal governance and preferences influence foreign policy and security decisions.
- Democracy and Globalization: Together, they reduce the likelihood of war by promoting shared values and interdependence.
- Interdependence and Trade: Economic ties make conflict less attractive, as the costs of war outweigh the potential benefits.
- Cooperation Beyond Hegemony: Unlike realist views, neoliberals argue that cooperation does not require dominance by a single powerful state; shared democratic and liberal values can sustain it.
Liberalism and the Question of Peace
Liberalism is often associated with a belief in the possibility of peace:
- The Cost of War: In modern societies, war is more costly than beneficial, making peace the rational choice.
- Democratic Peace Theory: Democracies rarely fight one another, since they share values of accountability, rights, and negotiation.
- Economic Interdependence: Trade and prosperity create strong incentives for peace.
- Challenges: Transitional democracies may still face instability and conflict. Historical examples include the Balkans, the Caucasus, and the Russia-Chechnya conflict.
Conclusion
Liberalism, both classical and neoliberal, provides a hopeful framework for understanding international relations. While classical liberalism highlights individual rights, democracy, and free markets, neoliberalism adapts these ideas to a globalized and interdependent world. Together, they suggest that cooperation, law, and institutions can reduce the likelihood of war and foster stability.
Unlike realism’s pessimism, liberalism envisions a world where democracy, capitalism, and human rights create the conditions for lasting peace.
